This chapter has enabled you to think about the essential role of technological change in determining economy-wide growth and the growth of firms and industries. We have seen that many issues surrounding the new economy are really issues around the dynamics of technological change: rapid increases in productivity, the emergence of many small firms, new products and new processes, and so on. The main lesson of the unit has been to provide a historical perspective to the introduction of new tec

In the USA, the automobile reached the 50 per cent household penetration rate in 1923, about 23 years into the industry's development. The PC reached that threshold rate in 1999, also about 23 years into its development. Given the discussion in Section 3, this suggests that the economy-wide effects of the PC have yet to be fully see

How did the turbulence caused by new firms entering and leaving the industry, radical technological change and falling prices affect the overall industry structure? The term ‘industry structure’ refers mainly to the way in which power is distributed among firms. This can be described by factors such as the number of firms in the industry and the distribution of market shares (the market share of a firm is its share of total industry production expressed as a percentage).

In both industries the fall in prices was driven by radical changes in the production of the products. How might we investigate the technological changes and the changes in quality that occurred in both industries simultaneously with the drastic fall in prices? There are various methods used by economists to measure technological change. Some methods focus on the ‘inputs’ into the innovation process, such as the spending on research and development by firms. But this is not ideal as it do

Many of the new entrants entered by introducing a new variation of the product. In fact, the early period in both industries was characterised by much technological change in the form of product innovation. Once a product standard emerged, product and process innovations around that standard led to a drastic fall in the product price in both industries. We will now look at some of the indicators of this turbulence in technology and prices.

How can we look at price changes over time in i

Both the automobile and PC industries were characterised by a great deal of turbulence in the first 20 to 30 years of their existence. In both cases, many new firms entered the industry, introduced new varieties of the product, and soon left the industry, leaving only a few dozen firms to compete during the growth phase. By 1926 only 33 per cent of the firms that had started producing automobiles during the previous 22 years had survived. In the case of PCs, by 1999 only 20 per cent of the fi

As you have now seen, the concept of the ‘new economy’ has inspired a number of studies that compare the effect that new technologies have had on economy-wide productivity in previous eras with the effect that IT has – or has not yet – had in the current era. I shall now ask another question, still along the lines of ‘what's new in the new economy?’, but this time from a more microeconomic perspective, which focuses on the individual firm and industry rather than on the whole econ

I have shown that, while IT has no doubt had an impact on productivity, it is not clear whether this goes beyond the IT-producing sector, or whether the gains will outlast the boom period of the business cycle. With so much debate, whom should we believe? Perhaps, as is often the case, the truth lies somewhere in the middle. The optimistic view highlights the way that IT has transformed society, and how this transformation has in many instances led to growth through the productivity-enhancing

Although the audio file included in this unit was designed to compliment the D218 Social Policy: Welfare, Power and Diversity Open University course its contents are still relevant to anyone wishing to improve their understanding of note taking. The audio file, however, uses specific examples associated with the Social Sciences.

The audio file was recorded in 1998. John Clarke discusses the value and best ways of note taking with OU colleagues Esther Saraga and Gerry Mooney.
